Smooth transitions may be provided between adjacent surfaces of the first cover 210, so that the first cover 210 has a smooth feel. It can be understood that chamfers may or may not be provided between the first bottom surface 214 and adjacent surfaces for smooth transitions. The second cover 220 includes a second outer surface 221 and a second inner surface 222 arranged opposite to each other, a second top surface 223 and a second bottom surface 224 arranged opposite to each other, and a second left side surface 225 and a second right side surface 226 arranged opposite to each other. Smooth transitions may be provided between adjacent surfaces of the second cover 220, so that the second cover 220 has a smooth feel. It can be understood that chamfers may or may not be provided between the second bottom surface 224 and adjacent surfaces for smooth transitions.

[0151] As Figure 5 and Figure 6aAs shown, in one embodiment, the first cover 210 and the second cover 220 can rotate relative to the body 100 about the width direction of the charger 10, such that the first cover 210 and the second cover 220 have a second state and a first state, that is, the charger 10 has a second state and a first state. In another embodiment, the first cover 210 and the second cover 220 can also rotate relative to the body 100 about the length direction of the charger 10. As Figure 6a shown, in the second state, the first cover 210 and the second cover 220 face away from each other. The first cover 210 fits against one side of the body 100, and the second cover 220 fits against the other side of the body 100. The end faces of the first cover 210, the second cover 220 connected to the body 100 are flush with the end face of the body 100 where the pins 300 are provided, that is, both the first bottom surface 214 and the second bottom surface 224 are flush with the second end face 106, and the pins 300 are exposed. It can be understood that being flush can be completely in one plane or there can be a height difference within a certain range. For example, the height difference between the end faces of the first cover 210, the second cover 220 connected to the body 100 and the end face of the body 100 provided with the pins 300 is not greater than 5 mm or not greater than 10 mm or other dimensions. Such a situation is also within the protection scope of this application. Similarly, fitting can mean that the two surfaces are completely in close contact without gaps, or there can be a certain gap between the two surfaces. For example, the gap between the surfaces of the first cover 210, the second cover 220 and the two sides of the body 100 is not greater than 1 mm or 2 mm or other dimensions. Such a situation is also within the protection scope of this application.

[0152] As Figure 2 and Figure 3 shown, in the first state, all structures of the pins 300 are covered by the first cover 210 and the second cover 220. The first inner surface 212 and the second inner surface 222 are in contact and touch each other. The first outer surface 211 is flush with the first surface 101, the second outer surface 221 is flush with the second surface 102, the first left side surface 215 is flush with the first side surface 103, and the first right side surface 216 is flush with the second side surface 104. The flushness between surfaces can be coplanar or there can be a slight height difference, all within the protection scope of this application. When the first inner surface 212 and the second inner surface 222 are in contact, there can be no gap between them or there can be a gap, such as the gap not being greater than 1 mm or 2 mm or other dimensions. In the first state, the charger 10 appears as an integral cuboid structure, with a good visual effect, and all the pins 300 are covered and hidden. When the user puts the charger 10 into a pocket or a suitcase, the charger 10 will not damage the surrounding objects. In another embodiment, in the first state, some structures of the pins 300 are covered by the first cover 210 and the second cover 220, and some structures are exposed outside the first cover 210 and the second cover 220.

[0153] In one embodiment, the first cover 210 is provided with a first card slot 217 (shown in Figure 8 ), the first card slot 217 extends to the first inner surface 212, and the shape of the first card slot 217 is similar to the shape of the pin 300; the second cover 220 is provided with a second card slot 227 (shown in Figure 8 ), the second card slot 227 extends to the second inner surface 222, and the shape of the second card slot 227 is similar to the shape of the pin 300. In the first state, the first card slot 217 and the second card slot 227 are in communication, and the pin 300 can be received in the first card slot 217 and the second card slot 227. In one embodiment, in the length direction of the pin 300, i.e., the Y direction, the first card slot 217 extends to the first bottom surface 214, but there is a certain distance from the first top surface 213; the second card slot 218 extends to the second bottom surface 224, but there is a certain distance from the second top surface 223; then in the first state of the charger 10, the pin 300 is completely hidden and not exposed, and the appearance of the charger 10 presents a complete cuboid or cube structure, ensuring the integrity of the appearance of the charger 10. In another embodiment, in the length direction of the pin 300, i.e., the Y direction, the first card slot 217 extends to the first bottom surface 214 and the first top surface 213, and the second card slot 218 extends to the second bottom surface 224 and the second top surface 223; that is, the lengths of the first cover 210 and the second cover 220 protruding from the body 100 are equal to the length of the pin 300. Then in the first state of the charger 10, the pin 300 is flush with the first top surface 213 and the second top surface 223 respectively, so that the length dimension of the charger 10 is smaller, thinner and lighter, and is convenient to carry.

[0154] In one embodiment, the number of pins 300 is 2, and the number of the first card slot 217 and the second card slot 227 is 2. In another embodiment, the number of pins 300 is 1, 3 or more, and the number of the first card slot 217 and the second card slot 227 corresponds to the number of pins 300.

[0155] In another embodiment, the first cover 210 is a hollow open box structure, and the second cover 220 is a hollow open box structure. In the first state, the first cover 210 and the second cover 220 form a closed internal space, the pin 300 is received in the internal space formed by the first cover 210 and the second cover 220, and the number of pins 300 is not limited.

[0156] Figure 6aAs shown, in one embodiment, compared with the first state of the charger 10, the first cover 210 and the second cover 220 are each rotated approximately 180° about the width direction of the charger 10. That is, when the charger 10 is in the first state, the first cover 210 and the second cover 220 are rotated 180° relative to the body 100, such that the first outer surface 211 is fixedly attached to the first surface 101, and the second outer surface 221 is fixedly attached to the second surface 102, and the charger 10 is in the second state.

[0157] As Figure 6a shown, in one embodiment, the number of pins 300 is two, and the two pins 300 are arranged in the width direction of the charger 10, i.e., the X direction. The distance between each of the two pins 300 and the first surface 101 is L1, and the distance between each of the two pins 300 and the second surface 102 is L2. When the charger 10 is in the second state, the distance between each of the two pins 300 and the first inner surface 212 is L3, and L3 is equal to the sum of the thickness of the first cover 210 and L1; the distance between each of the two pins 300 and the second inner surface 222 is L4, and L4 is equal to the sum of the thickness of the second cover 220 and L2. In the second state, the minimum distance of the pins 300 from the edge of the body 100 is the minimum value of L3 and L4.

[0158] Safety regulations require that, as stipulated in the safety regulations, when the charger 10 is in the second state, the distance from the pins 300 to the edge of the charger 10 is not less than a preset value. The preset value can be 6.5 mm, or it can be other data, which is specifically determined according to the usage of the charger 10. In one embodiment, L1 is equal to L2, that is, the two pins 300 are symmetrically arranged on the second end face 106, and L3 is equal to L4, then the minimum distance of the pins 300 from the edge of the body 100 is L3 or L4. L1 is less than the preset value, for example, 2.65 mm, and L3 is not less than the preset value, for example, 8.4 mm. In another embodiment, L1 is not equal to L2, that is, the two pins 300 are asymmetrically arranged on the second end face 106. For example, if the two pins 300 are close to the first surface 101, then L1 is less than L2, then L3 is less than L4, and the minimum distance of the pins 300 from the edge of the body 100 is L3; or, if the two pins 300 are close to the second surface 102, then L1 is greater than L2, then L3 is greater than L4, and the minimum distance of the pins 300 from the edge of the body 100 is L4. In this embodiment, both L1 and L2 are less than the preset value, and both L3 and L4 are not less than the preset value.

[0159] In the first state of the charger 10, the thickness of the charger 10 is the sum of the dimension of the pin 300 in the Z direction and L1 and L2. Both L1 and L2 are less than a preset value. When L1 and L2 are small, the thickness of the charger 10 is small. The charger 10 with a smaller thickness has an attractive appearance, a sense of technology, and is easy to carry. In the second state of the charger 10, it can meet the safety regulations requirements. That is, the charger 10 of the present application has a smaller thickness in the first state and is easy to carry; in the second state, the distance from the pin 300 to the edge of the charger 10 is increased by the fitting of the first cover 210, the second cover 220 and the body 100, so that the charger 10 can meet the requirements of safety regulations, that is, the requirements of safety specifications.

[0160] As Figure 6b described, in another embodiment, two pins 300 are arranged in the thickness direction of the charger 10, that is, in the Z direction, that is, one pin 300 is close to the first surface 101 and the other pin 300 is close to the second surface 102. In the second state, the distances of the two pins 300 from the edge of the first cover 210, that is, the first inner surface 212, are different, and the distances of the two pins 300 from the first surface 101 are different; the distances of the two pins 300 from the edge of the second cover 220, that is, the second inner surface 222, are different, and the distances of the two pins from the second surface 102 are different. Define the minimum distance from the pin 300 to the first surface 101 as L5, then the distance between the pin 300 close to the first surface 101 and the first surface 101 is L5; define the minimum distance from the pin 300 to the first inner surface 212 in the second state as L7, then the distance between the pin 300 close to the first surface 101 and the first inner surface 212 is L7; define the minimum distance from the pin 300 to the second surface 102 as L6, then the distance between the pin 300 close to the second surface 102 and the second surface 102 is L6; define the minimum distance from the pin 300 to the second inner surface 222 in the second state as L8, then the distance between the pin 300 close to the second surface 102 and the second inner surface 222 is L8. In this embodiment, the minimum distance from the pin 300 to the edge of the main body 100 is not less than the preset value, that is, both L7 and L8 are not less than the preset value; and in the width direction of the charger 10, that is, the X direction, the minimum distance from the pin 300 to the edge of the body 100 is not less than the preset value, that is, the minimum distance from the pin 300 to the first side surface 103 is not less than the preset value, and the minimum distance to the second side surface 104 is not less than the preset value. L5 and L6 may be equal or unequal, but both L5 and L6 are less than the preset value; L7 and L8 may be equal or unequal, but both L7 and L8 are not less than the preset value. In one embodiment, the preset value is 6.5 mm.

[0161] As Figure 7a and Figure 8As shown, in one embodiment, a first receiving groove 111 and a second receiving groove 121 are respectively formed on a first surface 101 and a second surface 102 of the body 100. A third receiving groove 218 is formed on a first outer surface 211 of the first cover 210, and the third receiving groove 218 is arranged opposite to the first card slot 217; a fourth receiving groove 228 is formed on a second outer surface 221 of the second cover 220, and the fourth receiving groove 228 is arranged opposite to the second card slot 227. The first receiving groove 111 and the third receiving groove 218 are communicated, and their depths and widths are the same; the second receiving groove 121 and the fourth receiving groove 228 are communicated, and their depths and widths are the same. It can be understood that the width of the first receiving groove 111 can be smaller than the width of the first surface 101, or can be substantially equal to the width of the first surface 101; the width of the second receiving groove 121 can be smaller than the width of the second surface 102, or can be substantially equal to the width of the second surface 102.

[0162] The charger 10 includes flexible elements. The first cover 210 and the body 100 are connected by the flexible elements to achieve rotation, and the second cover 220 and the body 100 are connected by the flexible elements to achieve rotation. The flexible elements include a first flexible element 610 and a second flexible element 620. A part of the structure of the first flexible element 610 is accommodated in the first receiving groove 111, and the remaining structure is accommodated in the third receiving groove 218. The thickness of the first flexible element 610 is equal to or substantially equal to the depths of the first receiving groove 111 and the third receiving groove 218. The first flexible element 610 can be flush with the first surface 101, or slightly protrude from the first surface 101 or slightly recess into the first surface 101. The first flexible element 610 can be bonded in the first receiving groove 111 and the third receiving groove 218, or can be mechanically fixed. A part of the structure of the second flexible element 620 is accommodated in the second receiving groove 121, and the remaining structure is accommodated in the fourth receiving groove 228. The thickness of the second flexible element 620 is equal to or substantially equal to the depths of the second receiving groove 121 and the fourth receiving groove 228. The second flexible element 620 can be flush with the second surface 102, or slightly protrude from the second surface 102 or slightly recess into the second surface 102. The second flexible element 620 can be bonded in the second receiving groove 121 and the fourth receiving groove 228, or can be mechanically fixed. In one embodiment, the materials on the sides of the first flexible element 610 and the second flexible element 620 are leather or mylar or silicone and other polymer materials, or other materials with flexibility, bendability or foldability, which are not limited herein.

[0163] The first cover 210 and the second cover 220 are respectively connected to the main body 100 through the first flexible element 610 and the second flexible element 620. Relying on the flexibility of the first flexible element 610 and the second flexible element 620, at the junctions of the first cover 210 and the second cover 220 with the main body 100 respectively, the first flexible element 610 and the second flexible element 620 can be rotated and bent freely, so as to realize the normal opening and closing of the charger 10. As Figure 3 , Figure 5 and Figure 6a shown, the first cover 210 and the second cover 220 can rotate relative to the main body 100 around the width direction of the charger 10, i.e., the X direction, so that the first cover 210 and the second cover 220 are arranged side by side with the main body 100 in the length direction of the charger 10, i.e., the Y direction, so that the charger 10 is in the first state, and the first flexible element 610 and the second flexible element 620 are in a flattened state. When the charger 10 needs to be opened, the first cover 210 and the second cover 220 are rotated around the width direction of the charger 10, i.e., the X direction, and the first flexible element 610 and the second flexible element 620 are bent, so that the first cover 210 and the second cover 220 are respectively attached to the opposite sides of the main body 100, so that the charger 10 is in the second state, and the first flexible element 610 and the second flexible element 620 are in a folded state.

[0164] It can be understood that the first flexible element 610 can cover the entire area of the first surface 101 and the entire area of the first outer surface 211, or can cover a partial area of the first surface 101 and a partial area of the first outer surface 211, as long as it can connect the first cover 210 to the main body 100 and enable the first cover 210 to rotate relative to the main body 100 around the width direction of the charger 10, i.e., the X direction. Similarly, the second flexible element 620 can cover the entire area of the second surface 102 and the entire area of the second outer surface 221, or can cover a partial area of the second surface 102 and a partial area of the second outer surface 221, as long as it can connect the second cover 220 to the main body 100 and enable the second cover 220 to rotate relative to the main body 100 around the width direction of the charger 10, i.e., the X direction.

[0165] As Figure 7a and Figure 8As shown, in one embodiment, the first cover 210 is provided with a first groove 219, and the first groove 219 extends to the bottom of the third receiving groove 218. A first magnetic member 510 is provided in the first groove 219, and a first flexible element 610 covers the first magnetic member 510. The second cover 220 is provided with a second groove 229, and the second groove 229 extends to the bottom of the fourth receiving groove 228. A second magnetic member 520 is provided in the second groove 229, and a second flexible element 620 covers the second magnetic member 520. There is a magnetic force between the first magnetic member 510 and the second magnetic member 520, so that there is a magnetic force of mutual attraction between the first cover 210 and the second cover 220. In one embodiment, the first magnetic member 510 and the second magnetic member 520 are both magnets. In another embodiment, one of the first magnetic member 510 and the second magnetic member 520 is a magnet, and the other of the two can be magnetically attracted by a magnet, such as an ordinary iron block.

[0166] In another embodiment, the first magnetic member 510 can be located on the first outer surface 211 or the first inner surface 212 of the first cover body 210, and the second magnetic member 520 can be located on the second outer surface 221 or the second inner surface 222 of the second cover body 220, which can also enable the existence of a mutual magnetic force of attraction between the first cover body 210 and the second cover body 220.

[0167] like Figure 3 As shown, in the first state, the first cover 210 and the second cover 220 are fixed by magnetic attraction through the first magnetic member 510 and the second magnetic member 520, and the magnetic force of the first magnetic member 510 and the second magnetic member 520 passes through the first inner surface 212 and the second inner surface 222. When the user puts the charger in a pocket or a suitcase, the first cover 210 and the second cover 220 hide the pins 300 to prevent the pins 300 from scratching surrounding objects, and the first cover 210 and the second cover 220 are not easy to open, so that the charger 10 can reliably hide the pins 300 during storage or transportation.

[0168] like Figure 3 , Figure 5 and Figure 6a As shown, in one embodiment, the magnetic force of mutual attraction between the first magnetic member 510 and the second magnetic member 520 includes a first magnetic force F1 and a second magnetic force F2. The first magnetic force F1 passes through the first inner surface 212 and the second inner surface 222, so that the first cover 210 and the second cover 220 have a tendency to rotate to the first state; the second magnetic force F2 passes through the first outer surface 211, the second outer surface 221 and the main body 100, so that the first cover 210 and the second cover 220 have a tendency to rotate to the second state.

[0169] When the charger 10 is in the first state, the first cover 210 and the second cover 220 are attracted and tightened by the first magnetic force F1 between the first magnetic member 510 and the second magnetic member 520 and do not open. When the first cover 210 and the second cover 220 need to be opened, the user needs to apply a force to the first cover 210 or the second cover 220 to overcome the first magnetic force F1 between the first magnetic member 510 and the second magnetic member 520, so that the first cover 210 or the second cover 220 can rotate relative to the body 100. There is a critical angle α, which is the angle between the first cover 210 or the second cover 220 and the body, that is, the angle between the first outer surface 211 and the plane where the first surface 101 is located, or the angle between the second outer surface 221 and the plane where the second surface 102 is located. When one of the first cover 210 and the second cover 220 is in the first state or the second state, and the angle between the other of the first cover 210 and the second cover 220 and the body 100 is the critical angle α, the first magnetic force F1 and the second magnetic force F2 are in a balanced state, that is, the first magnetic force F1 and the second magnetic force F2 interact to make the first cover 210 and the second cover 220 in a balanced state. When one of the first cover 210 and the second cover 220 is in the second state, and the angle between the other of the first cover 210 and the second cover 220 and the body 100 is greater than the critical angle α, the first magnetic force F1 is greater than the second magnetic force F2, and the first cover 210 and the second cover 220 can automatically return to the first state. When one of the first cover 210 and the second cover 220 is in the first state, and the angle between the other of the first cover 210 and the second cover 220 and the body 100 is less than the critical angle α, the first magnetic force F1 is less than the second magnetic force F2, and the first cover 210 and the second cover 220 can automatically return to the second state.

[0170] Assume that the user applies a force to the first cover 210, and the first cover 210 rotates while the second cover 220 remains stationary. At this time, the first magnetic force F1 is greater than the second magnetic force F2, causing the first cover 210 and the second cover 220 to tend to return to the first state. When rotating the first cover 210 from the first state and before reaching the state where the included angle between the first cover 210 and the body 100 is the critical angle α, the first magnetic force F1 gradually weakens, the second magnetic force F2 gradually strengthens, and the first magnetic force F1 is greater than the second magnetic force F2, causing the first cover 210 and the second cover 220 to tend to return to the first state. When the first cover 210 rotates to the included angle with the body 100 being the critical angle α, the first magnetic force F1 and the second magnetic force F2 are in a balanced state, enabling the first cover 210 and the second cover 220 to be in a balanced state. Ideally, the first cover 210 and the second cover 220 can remain stationary in this state. As the user continues to apply force, the first magnetic force F1 continues to decrease, the second magnetic force F2 continues to strengthen, but the first magnetic force F1 is always less than the second magnetic force F2. Then the user can stop applying force to the first cover 210, and the second magnetic force F2 causes the first cover 210 and the second cover 220 to automatically rotate relative to the body 100 until both the first cover 210 and the second cover 220 are attached to the body 100. When the charger 10 is in the second state and the user uses the charger 10 to supply power to the electronic component, the first cover 210 and the second cover 220 are fixedly attached to the body 100 and will not shake or rotate, which is convenient for use. It can be understood that when the charger 10 needs to be opened, the user can also choose to apply a force to the second cover 220, and can also open the charger 10, and the working principle is the same as the way the user applies a force to the first cover 210.

[0171] Such as Figure 3 , Figure 5 and Figure 6aAs shown, in one embodiment, when the charger 10 is in the second state, the first cover 210 and the second cover 220 are attracted and tightened by the second magnetic force F2 between the first magnetic member 510 and the second magnetic member 520 and do not open. When the charger 10 needs to be closed, the user needs to apply a force to the first cover 210 or the second cover 220 to overcome the second magnetic force F2 between the first magnetic member 510 and the second magnetic member 520, so that the first cover 210 or the second cover 220 can rotate relative to the body 100. Assuming that the user applies a force to the first cover 210, the first cover 210 leaves the body 100 and rotates, and the second cover 220 remains in contact with the body 100. As the first cover 210 rotates, the second magnetic force F2 weakens and the first magnetic force F1 gradually increases, but the second magnetic force F2 is always greater than the first magnetic force F1. When the angle between the first cover 210 and the body 100 reaches the critical angle α, the first magnetic force F1 and the second magnetic force F2 are in an equilibrium state, that is, the first cover 210 and the second cover 220 are in an equilibrium state under the combined action of the first magnetic force F1 and the second magnetic force F2. Ideally, the first cover 210 and the second cover 220 can be in a static state. As the user continues to apply a force to the first cover 210, the balance state between the first magnetic force F1 and the second magnetic force F2 is broken, making the first magnetic force F1 greater than the second magnetic force F2, and the user can stop applying a force to the first cover 210. The first magnetic force F1 can cause the first cover 210 and the second cover 220 to automatically rotate relative to the body 100 until the first cover 210 and the second cover 220 are attached and fixed, so that the charger 10 is in the first state. When the charger 10 is in the first state, during storage, transportation, daily placement, or movement, the first cover 210 and the second cover 220 are tightly fixed, having the reliability of hiding the plug 300, and are relatively thin and convenient to carry. It can be understood that when the charger 10 needs to be closed, the user can also choose to apply a force to the second cover 220, and the charger 10 can also be closed, and the working principle is the same as the way the user applies a force to the first cover 210.

[0172] In one embodiment, part or all of the structure of the first cover 210 is made of a magnetic material, and part or all of the structure of the second cover 220 is made of a magnetic material, so that there is a magnetic force of mutual attraction between the first cover 210 and the second cover 220. Thus, the automatic opening and automatic closing between the first cover 210 and the second cover 220 can be realized, and the implementation principle is the same as above and will not be elaborated here.

[0173] In one embodiment, part or all of the structure of the cover is made of a magnetic material, and part or all of the structure of the body 100 is made of a magnetic material, so that there is an attractive magnetic force between the cover and the body.

In the second state, the first cover 210 and the second cover 220 are attached and fixed, and at least part of the structure of the plug 300 is covered by the first cover 210 and the second cover 220; in the first state, the first cover 210 and the second cover 220 are respectively attached and fixed to both sides of the main body 100.

[0183] As Figure 9 and Figure 10As shown, in one embodiment, the pin 300 is fixed to the fixing base 400, or the pin 300 and the fixing base 400 that are fixedly integrated are directly purchased. It can be understood that the pin 300 and the fixing base 400 can be electrically connected, or the pin 300 can be electrically connected to a part of the structure on the fixing base 400, so that after the circuit board 700 is connected to the fixing base 400, the circuit board 700 can be electrically connected to the pin 300. The fixing base 400 is fixed to the first housing 110, so that the first rib 119 is clamped and fixed in the first channel 410.

[0184] As Figure 11 and Figure 12 As shown, in one embodiment, the circuit board 700 is provided and fixed inside the first housing 110.

It can be understood that there is a structure on the fixing base 400 that can conduct electricity and can be electrically connected to the pin 300, so that the circuit board 700 can be electrically connected to the pin 300.

[0185] As Figure 13 and Figure 14 As shown, in one embodiment, the second housing 120 is assembled and fixed to the first housing 110. In one embodiment, the second housing 120 and the first housing 110 are fixed by an ultrasonic hot melt process. In another embodiment, the second housing 120 and the first housing 110 can also be fixed by other processes. The second rib 129 is clamped in the second channel 420, and the first housing 110 and the second housing 120 together firmly clamp and fix the fixing base 400, so that the plug and unplug life of the charger 10 is reliable.

[0186] As Figure 2 and Figure 7a As shown, in one embodiment, the first magnetic member 510 is fixed in the first groove 219, and the second magnetic member 520 is fixed in the second groove 229. The first flexible element 610 is adhesively fixed or mechanically fixed in the first receiving groove 111 and the third receiving groove 218 and covers the first magnetic member 510, thereby connecting the first cover 210 to the first housing 110. The second flexible element 620 is adhesively fixed or mechanically fixed in the second receiving groove 121 and the fourth receiving groove 228 and covers the second magnetic member 520, thereby connecting the second cover 220 to the second housing 120. The first flexible element 610 and the second flexible element 620 are flexible, so that the first cover 210 and the second cover 220 can be opened or closed along a certain trajectory of the charger 10, so that the pin 300 is exposed or hidden.

[0187] When the charger 10 is in the first state, based on the principle of the magnetic fields of the first magnetic member 510 and the second magnetic member 520, when the first cover 210 or the second cover 220 is opened to the critical angle α, the second magnetic force F2 between the first magnetic member 510 and the second magnetic member 520 is greater than the first magnetic force F1, thereby realizing the automatic opening of the first cover 210 and the second cover 220 and being able to keep the open state all the time. Similarly, when the charger 10 is in the second state, when the first cover 210 or the second cover 220 is closed to the critical angle α, the second magnetic force F2 between the first magnetic member 510 and the second magnetic member 520 is less than the first magnetic force F1, and the first cover 210 and the second cover 220 will also automatically close and maintain the first state by relying on the magnetic force.

[0188] The charger 10 has a relatively thin thickness. In the unused state, the charger 10 can be placed in the first state, the pins 300 are hidden, the appearance is complete, it has portability, and the pins 300 will not damage surrounding objects. When the charger 10 is in the second state, the first cover 210 and the second cover 220 are attached to the main body 100, so that the charger 10 meets the safety regulations requirements. Utilizing the magnetic field characteristics of the first magnetic member 510 and the second magnetic member 520, after the first cover 210 or the second cover 220 is opened or closed to the critical angle α, the first cover 210 and the second cover 220 can together realize the function of automatic opening or closing, improving the user experience. The first flexible element 610 and the second flexible element 620 respectively connect the first cover 210 and the second cover 220 to the main body 100, which can save the rotating mechanism. At the same time, the first flexible element 610 and the second flexible element 620 are the appearance of the charger 10, and visually it is a complete plane, making the charger 10 have a complete appearance.

In the first state, the cover 80 covers the end of the main body 100, and at least part of the structure of the pin 300 can be received in the cover 80. The entire structure of the pin 300 can be received in the cover 80, or part of the structure can be exposed. In the second state, the cover 80 is opened and stacked on one side of the main body, and the cover 80 is attached to the surface of the main body.

There is a magnetic force of mutual attraction between the sixth magnetic member 901 and the eighth magnetic member 903; there is a magnetic force of mutual attraction between the seventh magnetic member 902 and the ninth magnetic member 904. In the first state, the cover 80 and the body 100 are magnetically fixed by the magnetic force of mutual attraction between the sixth magnetic member 901 and the eighth magnetic member 903. In the second state, the cover 80 and the body 100 are magnetically fixed by the magnetic force of mutual attraction between the seventh magnetic member 902 and the ninth magnetic member 904. During the rotation of the cover 80, when the magnetic force between the sixth magnetic member 901 and the eighth magnetic member 903 is greater than the magnetic force between the seventh magnetic member 902 and the ninth magnetic member 904, the cover 80 can automatically rotate to the first state and maintain the first state. When the magnetic force between the sixth magnetic member 901 and the eighth magnetic member 903 is less than the magnetic force between the seventh magnetic member 902 and the ninth magnetic member 904, the cover 80 can automatically rotate to the second state and maintain the second state.
